JET-CONDENSER."

SPECIFICATION forming part of Letters Patent No. 293,791, dated February19,1884 Application filed December 10, 1883. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS SoHUrrE, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have inventedcertainlmprovements in J et- Condensers, of which the following is aspecification. t

This invention has reference to what are commonly known in the art aswater-jet condensers, which are constructed in various forms, differingfrom each other only in matters of detail, an excellent type of whichmay be found in Letters Patent of the United States No. 285,6 4, datedOctober 2, 1883.

The object of the present invention is to make provision for aregulation of the capacity of the apparatus, and thereby the regu- Whilea single jet-condenser allows of but little or no regulation in theconsumption of water, it may be applied within certain ranges; but wherethe apparatus is larger than necessary there will be an excess of waterused, and where the apparatus is not of sufficient size thevacuumproduced will be less than it would otherwise be. In most casesthis difference in result will be so small as to be practicablyadmissible; but there are conditions encountered in practice wheretherange is so wide that means must be provided to reduce the size ofthe apiaratus. To this end I combine several jet-- condensers, each"independent of the other, with sources of supply common to the series,and with valves or equivalent means by which either condenser may bethrown into or out of action independently of the others.

In the accompanying drawings, Figure 1 represents a central longitudinalsection through an apparatus or system containing three condensers orsetsof jet apparatus. Fig. 2' represents a cross-section of thewater-inlet and water-tube modified to answer the requirements when anadditional steam-jet may be demanded to supply water-to the condenser.

under suction. Fig. 3' represents a cross-sec tion of thewater-discharge modified in form to render the valve automatic. Fig. 4is a side elevation, illustrating my apparatus in com bination with anexhaust pipe and pump.

Referring to Fig. 1, A represents a pipe or conductor through which thewater is introduced into the apparatus; B, a' pipe or conductor throughwhich the water is finally delivered; and G, a body or chamber with therespective ends of which the supply and delivery pipes are connected, asshown. The chamber or tube 0 is provided with an inlet, E, in one side,through which it is sup plied with exhaust-steam.

.Within the body '0, Imonnt a three-jet apparatus, D, each consisting ofa water-tube, a,

a combining or mixing'tube, b, and a flaring delivery-tube, c, which, inthe present instance, are substantially identical in form andarrangement with those represented in Patent No. 285 329, beforereferred to. Each of the condensers D communicates at one end with thewater-supply A and at the opposite end with the delivery-tube B. Attheir upper'or receiving ends each condenser is provided with avalve, F,by means of which its communication with the water-supply may he closed.The lower or delivery end of each condenser, or the chamber in which itdischarges,is provided with avalve, G, by means of which communicationbetween the con denser and the delivery-pipe B may be closed. Under theabove arrangement it will be seen that by means of the two valves F andG at its opposite ends either one of the condensers B may be placed inor shut off from communi cation with the supply and delivery tubes atwill, independently of each other. In this manner the capacity of theapparatus, consid ered as a whole, may be varied as conditions mayrequire, in order to secure the highest degree of economy andefficiency.

Referring to Fig. 4, which illustrates one of the applications of my jetapparatus, K represents a steam-pump; L, the. body of thecondelivery-pipe to convey water from the condenser to the suctionsideof the pump; 0, the water-supply to the condenser.

My apparatus will be of advantage in either of two cases: first, wherethe primary object is to pump water in varying quantities the condensermay be placed in the suction-pipe to condense the steam or create avacuum, and 1 thus relieve the pump of a portion of the work I withhandwheels; but valves of any suitablewhich it would otherwise berequired to perform; secondly, where the primary object is to create ormaintain a vacuum or condense steam of varying volume and deliver thewater to a higher level. The vacuum maintained in condensers of thisclass depends to some extent on the speed with which the water entersand traverses the combining-tube. If, therefore, a definite quantity ofwater is being pumped, the combined areas of the differentsets ofcombining-tubes should correspond to this quantity. If the quantity ofwater be too small, an undue increase in temperature, and a consequentreduction in vacuum, will result, while on the other hand an excess inarea of the tubes will cause the flow to be slow and will result in acorresponding decrease in the vacuum. It will be seen, therefore, thatto obtain the full advantage of the circumstances which may beencountered in each case it is of importance to have a regulation incapacity such as my combination of two or more condensers will effect.

I have represented in Fig. l the valves G, in the ordinary form ofscrew'valves provided form or construction may be employed. It is alsoobvious that the form of the apparatus and the arrangement of thepassages may be modified to any extent desired, provided two or morecondensers are adapted to be thrown into and out of action at will, withsupply and delivery passages common to the series. The water enteringthe pipe A will pass through such valves F as may be open, and thencethrough the communicating water-tube a, the combining-tube b, andfinally through the valve G to the discharge B. In the course of itspassage through the combining-tube the water will be acted upon and willcombine with and will have the. effect of condensing and carryingforward the steam which enters through the openings or inlets in thetube 1).

I11 certain cases it is necessary to lift the water to the apparatus.For this purpose I propose to provide a supplemental steam-jet, in thesame or substantially the same manner as represented in Patent No.285,846. In Fig. 2, I is a nozzle or jet-tube provided withcontrolling-valves and adapted to deliver live steam into the nozzle ofthe water-tube a.

In the modification of the discharge-valves represented in Fig. 3 itwill be observed that the valves proper are check-valves opening outwardinto a common passage, so as to be opened by the outflowing water.Opposite each valve there is a handscrew, by means of which the valvemay be forced to its seat, and thus held in a closed condition. Theoutwardly-opening valves thus applied are closed automatically in theevent of there being a vacuum. within the apparatus, and for this reasonthey are of advantage in certain cases.

Having thus described my invention, what I claim is 1. The combinationof two or more waterjet condensers, each comprising a water-tube, acondensing-tube, and a discharge-tube, with sources of water supply anddelivery common to the series, and means, substantially as described,whereby the condensers may be thrown into and out of actionindependently.

2. In combination with two or more jet-condensers, each comprising awater-tube, a combining-tube, and a discharge-tube, a pipe or dischargeforming a water-inlet common to the series, a pipe or discharge forminga wateroutlet common to the series, and an exhaustinlet also commontothe entire series.

3. The combination, with two or more jetcondensers combined with inletsand outlets common to the series, of check-valves combined with thedischarge ends of the respective condensers.

4. The combination,withthc series of jet-coir densers communicating i'ith a discharge pipe or passage common to the series, of thecheckvalves communicating with the individual condensers, and means,substantially as described, for holding said check-valves in closedpositions independently of each other.

5. In combination with two or more jet-condensers, each having awater-tube, a combiningtube, and a discharge-tube and separateclosing-valves, a casing provided with a common water-inlet, a commondischarge-inlet, and an exhaust-inlet, an exhaust-connection from anengine, anda suction-pipe to apump, substantially as described.

6. In combination with a jet-condensing apparatus comprising two or morejet-condensers and 'valves for placing the same independently into andout of action, substantially as described, a steam-pump, a conductordelivering the exhaust-steam therefrom to the series of I05 condensers,and a delivery-pipe forming a communication between the delivery ends ofthe condensers and the suction-port of the pump, whereby theexhauststeam is applied to assist in delivering the water to the pump.
